Design and Analysis of an Inset Feed X-Band Microstrip Patch Antenna

Abstract

Newer microwave and millimeter-wave systems are in higher demand to satisfy emerging communications difficulties in terms of size, bandwidth, and gain. As a result, antennas are commonly utilized to meet satellite communication demands. Different applications are accessible in different frequency ranges in satellite communication. Researchers are constantly trying to enhance the bandwidth and gain for Microstrip Patch antennas (MPAs). Using the Ansys HFSS and CST Studio Suite 3D EM simulation software a new optimized MPA is designed. The proposed antenna is an inset feed partial ground MPA structure that has resonance frequencies of 8.45 GHz, 9.95 GHz, and 13.17 GHz, with a bandwidth of 6.7 GHz. It operates at frequencies ranging from 7.9 GHz to 14.6 GHz covering the complete Xband and lower portion of Ku band. The planned antenna is 23.8×28.2×1.6 mm3 in size, with FR-4 Epoxy as the substrate which has a dielectric constant of 2.2 and loss tangent of 0.02. The antenna can be used for terrestrial broadband, uplink and downlink of satellite, mobilesatellite service, broadcasting satellite services, secure military communication, military satellite communication, direct broadcast satellite TV relay, fixed satellite service, amateur radio, weather monitoring , air traffic control, maritime vessel traffic control and radar application.
